Area of rectangle= base x height
6x4=24
Area of triangle= 0.5 base x height
We have the height but we don’t have the base, to calculate the base we subtract 10-6 which equals to 4
0.5 x 4 x4 =8
Area of a semicircle= o.5 x pi x r^2
We have the diameter and to find the radius we divide it by 2
4/2 = 2
0.5 x pi(or 3.14) x 2^2
=6.28
Total area = 24 + 8+ 6.28 =38.28cm^2
Average speed = dist/time
v = (17/5) ÷ (7/8)
v = (17/5) x (8/7)
v = (17 x 8) ÷ (5 x 7)
v = 136 ÷ 35
v= 3 + (31/35)
v = 3 31/35
Answer:
x=1
Step-by-step explanation:
10*3 = 30 (three rows of fences)
30*1.75 = $52.5
Hope this helps! :)
